Answer:
They can make 361 cheeseburguers. Since each costumer gets two cheeseburguers the restaurant can serve up to 180 costumers.
Explanation:
The material they have to produce cheeseburguers is 90 1/3 pounds wich is the same as 90.3334 pounds and each cheeseburguer they make takes 1/4 pounds or 0.25 pounds from this meat. In order to compute how many cheeseburguers they can make we can divide the total of meat by the amount of meat that goes on each meal. So we have:
number of cheeseburguer = (total of meat)/(meat of each burguer)
number of cheesburguer = 90.3334/0.25 = 361.3336
To round up they can make 361 cheeseburguers.
